Abstract
The aim of this study was to confirm that coordination and storage in the context of processing are significant predictors of reasoning even if crystallized intelligence is controlled for. It was also expected that sustained attention and coordination would be highly correlated. Therefore, 20 working memory tests, 2 attention tests, and 18 intelligence subtests were administered to 121 students. We were able to replicate results indicating that storage in the context of processing and coordination are significant predictors of reasoning. Controlling for crystallized intelligence did not decrease the common variance between working memory and reasoning. The study also revealed that the factors coordination and sustained attention were highly correlated. Finally, a model is presented with the latent variables speed and g, which can explain almost all of the common variance of the applied aggregates. A detailed discussion of the results supports the view that working memory and intelligence share about 70% of the common variance.
